Abstract: Embodiments include a method for managing connections to one or more antennas in a wireless network. In one embodiment, a method includes receiving antenna information at a wireless controller from an antenna. Configuration information is accessed from a database coupled to the wireless controller, where this information includes suitable antenna characteristics for use with the wireless network. The received antenna information and the configuration information are compared, and instructions are provided to cause the antenna to be connected to or disconnected from the wireless network based on the comparison between the antenna information and the configuration information.

Abstract: A scalable Ethernet switch includes modules which can be interconnected to provide a single, virtual switch. The modules may be of uniform physical size and shape relative to a standard telecommunications rack. When greater capacity is required, an additional module is mounted in a rack and interconnected with the other modules, e.g., in a bi-directional ring. Enhanced port density is provided by interconnecting the modules with 12 GbE links which operate on standard 10 GbE wiring and connectors. Consequently, throughput between modules in increased relative to standard 10 GbE links without increasing form factor. Further, transmission power control can be implemented such that modules of the virtual switch may be physically adjacent or separated by distances of several meters.

Abstract: A pump used to infuse a fluid into a patient is controlled in accordance with an algorithm that enables a microprocessor to monitor and adjust each pump cycle to compensate for a differential pressure between the pump's inlet and outlet. The algorithm defines a fluid delivery protocol that is applied in controlling the operation of the pump to achieve a desired rate, volume, and timing of the fluid infusion. Fluid is delivered by the pump when a plunger compresses an elastomeric membrane overlying a fluid chamber. Due to the small volume of the chamber, an incremental change in the plunger position before the delivery stroke produces a significant change in the delivery pressure. At the beginning of a pump cycle, the microprocessor determines the differential pressure between the inlet and outlet of the pump, and adjusts the plunger position before the delivery stroke to compensate for the differential pressure.
